A decision Wednesday by Front Range schools to cancel classes during a massive manhunt for a young woman believed to be a threat reignited unresolved debates over the role of guns in Colorado classrooms and American society. Hundreds of schools from Fort Collins to Douglas County were shuttered during the search for 18-year-old Sol Pais, an armed Florida woman who police said was “infatuated with Columbine.” Pais was found dead near Mount Evans on Wednesday morning. For partisans and ideologues on both sides of the national gun debate, Pais’ threats and the closures they caused only reinforced their views.
